2. Spectrum analyzer - Wikipedia

   en.wikipedia.org/wiki/Spectrum_analyzer

   Spectrum analyzers are widely used to measure the frequency response, noise and distortion characteristics of all kinds of radio-frequency (RF) circuitry, by comparing the input and output spectra. For example, in RF mixers, spectrum analyzer is used to find the levels of third order inter-modulation products and conversion loss.

3. Radio-frequency sweep - Wikipedia

   en.wikipedia.org/wiki/Radio-frequency_sweep

   A spectrum analyzer is a standard instrument used for RF sweep. It includes an electronically tunable receiver and a display. The display presents measured power (y axis) vs frequency (x axis). The power spectrum display is a two-dimensional display of measured power vs. frequency. The power may be either in linear units, or logarithmic units ...

4. Spectral density - Wikipedia

   en.wikipedia.org/wiki/Spectral_density

   Electronic instruments called spectrum analyzers are used to observe and measure the power spectra of signals. The spectrum analyzer measures the magnitude of the short-time Fourier transform (STFT) of an input signal. If the signal being analyzed can be considered a stationary process, the STFT is a good smoothed estimate of its power spectral ...

6. Network analyzer (electrical) - Wikipedia

   en.wikipedia.org/wiki/Network_analyzer_(electrical)

   vector network analyzer (VNA)—measures both amplitude and phase properties; A VNA is a form of RF network analyzer widely used for RF design applications. A VNA may also be called a gain–phase meter or an automatic network analyzer. An SNA is functionally identical to a spectrum analyzer in combination with a tracking generator.

7. Drive testing - Wikipedia

   RF Spectrum Analyzer - A device used to measure the entire radio spectrum concurrently. RF Scanners - A device used to measure radio frequency (RF) of multiple operators concurrently. RF layer 2 and RRC layer 3 capable tools - These are required for deep analysis on 4G and 5G networks and are usually expensive.
